THOMAS FARR, OF SUTTON-COLDFIELD, ENGLAND.

LAWN-movan.

Application led November 5, 1907.

To all whom it may concern:

Be it known that I, THOMAS FARR, a subject of the King of Great Britain,residing at Granvillef Maney Hill Road, Sutton- Coldiield, in the countyof Warwick, England, gentleman, have invented certain new and usefulImprovements in Lawn-Mowers, of which the following is a specification.

This invention provides an improved grass-box for lawn-mowing machines,having means mounted and working in it for clearing the grass from theknives, thus keeping the blades cleaner and consequently sharper, andconsiderably improving the working of the machine, while saving the timehitherto wasted in frequently emptying the box, as a larger' box can beused.

The means for clearing the grass from the lower edge of the box, whichis usually adjacent to the machine knives, and conveying the same to thefar end and back of the box, comprise a rake, or a series of rakes,Scrapers, or the like, mounted to rotate in the box, or to travel withan endless band, chain, or the like therein.

These rakes, scrapers, or the like, may be driven by a roller under thebox bearing on the ground or by any other means.

On the drawings appended to this specification: Figure l is a sectionalview, partly through the grass-collecting box, of a lawn mower accordingto this invention, and Fig. 2 is a fragmentary plan view thereof.

In this example the rakes A are mounted on endless bands, chains or thelike B, inside the box. The rakes may be mounted on the bands by smallpins and nuts passing through extended flanges formed at the ends of therakes, or by any other means. The bands B as shown, are passed over aroller b1 at the lower end of the box and over a roller b2 at the upperend of the box. The roller or shaft b2 is driven by bands c1 frompulleys, mounted on the spindle of a roller C bearing on the ground.This roller C would preferably be roughened or milled to improve itsgrip.

The front end of the box is provided with eye pieces D serving fortaking over projections or plates on the mower to secure the box inposition; any locking means such as pegs through perforations in aplate, simple cotters or other means may be provided in conjunction withthis.

The box illustrated is mounted at the back of the lawn mower in the sameposition as an Specication of Letters Patent.

ordinary box made to follow the machine; the approximate position of theknives is indicated by the dotted circle E. rlhe box which is providedwith lugs D with holes is made to iit over slotted projections h1 whichare carried on the arms H attached to the disk pieces G on the inside ofthe wheels F. The box is secured by means of pins or other suitablefasteners passing through the slot in the projection h1 as shown on thedrawings. As the box is thus moved along with the mower its drivingroller C is rotated imparting motion, through the band c1 to the rolleror shaft b2 and thus driving the endless bands B and conse uently therakes A. The rakes following t e movement of the band pass close to themachine knives clearing the cut grass from same and conveying it in asure and eective manner toward the back of the box. By the employment ofsuch a device it is obvious that a much larger box can be used than waspossible with machines where no means for carrying away the grass werepro vided. In this way a double advantage is obtained as the knives arekept clean and more effective in their working and the time of theoperator is saved, as it is not necessary 'for him to em ty the boxfrequently and use his hands for c caring the grass to the back of thebox as has hitherto been the case.

It must be understood that the invention admits of more ways of carryingout than the sim le form here shown, but that is quite su cient toenable the same being properly understood and its applicationsappreciated.

Any suitable gearing may be used for driving the rakes and it may beconnected up to any convenient moving part of the mower if desired,instead of to a separate driving roller.

What I claim then is:

l. A lawn mower provided with cutting knives, in combination with agrass box provided with rollers and having mechanical means for rakingthe cut grass from the front to the back of tne box, in a directioncorresponding to the disposition of the box bottom, said meanscomprising rakes mounted to travel round the rollers from the rear ofthe knives toward the end of the box remote from the knives.

2. The combination, with a grass box for a lawn mower, of rollerslocated at the front and back of the box and carrying endless bands,cutting knives, rakes placed on said bands for moving the cut grass fromthe underside of the front roller near to the knives up to the end ofthe box which is remote from the cutters, and mechanical means foractuating said rollers.

3. In a lawn mower, a Grass box having in combination a driving ro erJfor bearing on the ground, means for connection of the box to themower, a shaft across the top of the box, driving means from said rollerto said shaft, said shaft being provided with a roller, a roller at theend of the box nearest said connecting means, knives adjacent to saidlast-named roller, endless bands passing over said rollers and grasscollecting means secured to said endless bands and caused thereby totravel close to the revolving knives of the mower and then on theunderside of the rollers to the back of the box.

In testimony whereof, the said THOMAS FARR has signed his name to thisspecification in the presence of two subscribing witnesses, this 26thday of October 1907.
